Topic: 1975 CB750F - What is the best vendor for swing arm bushings?

[Mekagojira]

and for rear wheel bearings?

Yes, I'm a noob - there is a lot of info here but not much consensus...


Thanks

As an option, you might PM Hondaman on this. He offers a great Swing Arm Bushing Service. He's a valued member here and a good, honest fellow.

Try your local bearing shop for the bearings, they are a common standard size. I suggest double sealed bearings, not the single sided dust shield type originally installed. This would be a 620x-2RS rather than a 620x-z. The actual part number (6202, 6203, whatever, is stamped on the dust shield of the old bearing or you can find a list online of what you need. Precision code E3 is what's usually stocked and this is fine for wheels.

+1 on Hondaman . He will fit the bronze bushings to the swingarm and shaft . You will likely never need to take it apart again .

I found my Timken rear wheel bearings on Amazon.com (but they kept pushing back the ship date and eventually took 3 months to ship!). 
Got my SKF front wheel bearings from mscdirect.com.  (They arrived in about 3 days.)
I went after the brands that everyone on here claims are the best to be safe because I don't really know any better.  You can also get "all balls" brand from a bunch of different places and people seem to say that they're ok.

If you know the part number you need you can even get autozone or advance auto to order them for you.  They had mine listed as an alternator bearing I think.  Come to think of it I wonder if something they sell for an alternator will be tough enough to go in a wheel?  I had them order a specific Timken part number, and a different brand ended up coming in its place, but I don't remember what it was.  I returned it and ordered from MSCdirect.com.

I found all of the part numbers and sizes that I needed for my bike by searching old posts in this forum.
hope this is helpful.

This is the fiche for your rear wheel:

The bearings are numbers 37 and 38.  Down in the parts list you'll see "37: BEARING (6304U)" and "38:
BEARING (6305U)."  The 6304 and -05 are the bearing sizes.  A Google Shopping search for 6304-2RS (2 rubber shields?) gives you a ton of options, or you can try your local bearing supplier.  And take note that you need two 6304s.

I recently bought all the wheel bearings for my 550 from VXB (http://www.vxb.com/) because they had decent prices and Google checkout, and my local bearing place is open the same hours I'm at work.  I even splurged on the swanky Japanese made ones because, well, why not?

I think 2RS means 2 seals instead of shields.  The way I understand it double sealed bearings last longer and you don't have to re-grease them.  Don't get the part that ends in "U".  They're unsealed.  I was looking for the thread where I got all my info but I can't find it.  There's tons of information already in there somewhere though.  Search box is your friend.

Yep, yep, yep, seals and shields are not the same thing.  Good catch.
